as I can guess from the description (the download still in progress
), Deluxe is Full edition plus video tutors, additional reference materials et al. Maybe it's the same as "Plus" (however, "Plus" is a physical shipment, and Deluxe is both physical and electronic).
Full is 11 MB, and Deluxe is about 1GB in size. No program can be as big if only the distribution does not include videos.
